About these guidelines

The purpose of these application guidelines is to provide guidance in the application of Copeland
Scroll Digital™ Receiver Units HLR. They are intended to answer the questions raised while
designing, assembling and operating a system with these products.

Besides the support they provide, the instructions listed herein are also critical for the proper and
safe functioning of the receiver units. Emerson will not guarantee the performance and reliability of
the product if it is misused in regard of these guidelines.

These application guidelines cover stationary applications only. For mobile applications, contact
Application Engineering as other considerations may apply.

1 Safety instructions

Copeland Scroll Digital Receiver Units HLR are manufactured according to the latest European and
US safety standards. Particular emphasis has been placed on the user's safety.

HLR Digital Receiver Units are intended for installation in machines and systems according to the
Machinery directive MD 2006/42/EC. They may be put to service only if they have been installed in
these systems according to instructions and conform to the corresponding provisions of legislation.
For relevant standards please refer to the Manufacturer’s Declaration and other declarations
available at www.climate.emerson.com/en-gb.

These instructions should be retained throughout the lifetime of both the compressor and the unit.

You are strongly advised to follow these safety instructions.

danger of explosion.

1.2 Safety statements

▪ Refrigerant compressors must be employed only for their intended use.
▪ Only qualified and authorized HVAC or refrigeration personnel are permitted to install,

commission and maintain this equipment.

▪ Electrical connections must be made by qualified electrical personnel.
▪ All valid standards for connecting electrical and refrigeration equipment must be

observed.

▪ The national legislation and regulations regarding personnel protection must be

observed.

Use personal safety equipment. Safety goggles, gloves,

protective clothing, safety boots and hard hats should be worn
where necessary.

1.3 General instructions

WARNING
System breakdown! Personal injuries! Never install a system in the field

and leave it unattended when it has no charge, a holding charge, or with the
service valves closed without electrically locking out the system.
System breakdown! Personal injuries! Only approved refrigerants and
refrigeration oils must be used.

WARNING
High shell temperature! Burning! Do not touch the compressor until it has

cooled down. Ensure that other materials in the area of the compressor do
not come into contact with it. Lock and mark accessible sections.

CAUTION
Overheating! Bearing damage! Do not operate compressors without

refrigerant charge or without being connected to the system.

CAUTION
Contact with POE! Material damage! POE lubricant must be handled

carefully and the proper protective equipment (gloves, eye protection, etc.)
must be used at all times. POE must not come into contact with any surface
or material that it might damage, including without limitation, certain
polymers, eg, PVC/CPVC and polycarbonate.

IMPORTANT
Transit damage! Compressor and/or unit malfunction! Use original

packaging. Avoid collisions and tilting.

The contractor is responsible for the installation of the unit and should ensure that there is sufficient
liquid sub-cooling in the line to the expansion valve(s) to avoid "flash-gas" in the liquid line.

It is of vital importance that the discharge stop valve has been fully opened before the compressor
is started. If the discharge stop valve is closed or partly closed an unacceptable pressure with
accordingly high temperatures may develop on the discharge outlet in the compressor. When
operating with air the so-called diesel effect may occur, ie, the air sucked in is mixed with oil gas
and can explode due to the high temperature, and thereby destroy the compressor.

2 Product description

2.1 Common information about Copeland Scroll Digital™ Receiver units HLR

Emerson has developed the Copeland Scroll Digital™ Receiver Units HLR to meet refrigeration
demands for compact solutions at highest efficiency levels. These units allow continuous capacity
modulation from 10% to 100% and can be combined with various condenser concepts.

2.2 Product range

The range features ZB Scroll Digital™ compressors for medium temperature applications. It
consists of four models: two models including one compressor, and two models including two
compressors.
